ROSE PLANT Filed May 8, 1969 United States Patent 3,051 ROSE PLANT Jan Spek, Boskoop, Netherlands, assignor to Jackson & Perkins Company, Newark, N.Y. Filed May 8, 1969, Ser. No. 823,194 Int. Cl. A01h /00 US. Cl. Plt.29 1 Claim The present invention relates to a new and distinct variety of rose plant of the floribunda class, which was discovered by me as a sport of the rose variety known as Nordia (US. Plant Patent No. 2850).

At the time of my discovery, 1 was growing the variety Nordia in my nursery at Boskoop, Holland, and while tending the same, my attention was attracted to one particular plant which bore some flowers of a color significantly different than the color of the flowers on the rest of the plant and the other plants of Nordia. Upon close inspection of that particular plant, I found that it had sported, and I thereupon took steps tocarefully preserve the sport and to keep it under close observation. In due course, I asexually reproduced the sport by budding, as performed in my nursery at Boskoop. Continued observations and tests of the new sport and the progeny derived therefrom have convinced me that it is a new and distinct variety which is definitely distinguished from its parent, as well as from all other rose varieties of which I am aware, as evidenced by the following unique combination of characteristics which are outstand ing in the new sport:

(1) A similarity substantially identical in all respects to the parent variety Norida, except for the color of the buds and open flowers;

(2) A capability of being forced without going blind;

(3) A continuous blooming habit under forcing conditions; and

(4) A distinctive, attractive, truer and deeper red color of the buds and open flowers, correspongng to near Cardinal Red, as compared to the lighter and more Scarlet Red flower color of Nordia.

Additional asexual reproduction of the new variety by budding, as performed on my behalf at Newark, N.Y., U.S.A., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the foliage, stems and flowers of my new variety in different stages of development, and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new variety, with color terminology in accordance with Wilsons Horticultural Colour Chart, except where general color terms of ordinary dictionary significance are obvious:

I claim: 1. A new and distinct variety of rose plant of the flori- 4 bunda class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of a similarity substantially identical in all respects to the parent variety Nordia, except for the color of the buds and open flowers, a capability of being forced without going blind, a continuous blooming habit under forcing conditions, and a distinctive, attractive, truer and deeper red color of the buds and open flowers, corresponding to near Cardinal Red, as compared to the lighter and more Scarlet Red flower color of Nordia.
